Istio doesn‘t push custom ingressgateway traces to jaeger

HI guys,
I’ve configured my istio operator with two ingressgateway, one is default and the other renamed to ingressgateway-internal like

      name: istio-ingressgateway-internal
      label:
        istio: istio-ingressgateway-internal

But in jaeger, there are only traces from the default gw. Not sure where I did wrong , any clues?
